Your argument appears to misunderstand both the scientific principles behind climate change and the nature of the Earth's atmosphere. Let's address the key points:
Adiabatic Atmosphere: The Earth's atmosphere is not entirely adiabatic. While adiabatic processes (where no heat is exchanged with the surroundings) do occur, they are part of a complex system involving radiative, conductive, and convective heat transfers. The overall climate system involves significant heat exchange with space.
Greenhouse Gases: Greenhouse gases like CO2 and methane are well-documented to trap heat in the atmosphere. This is not about placing a blanket between the sun and the Earth, but rather about these gases allowing sunlight to enter and then trapping some of the heat that the Earth radiates back towards space. This trapped heat results in a warming effect, which is the essence of the greenhouse effect.
Heat Source Misunderstanding: Your analogy of a blanket causing cooling by insulating the planet from the sun is incorrect. Greenhouse gases do not block sunlight; they trap infrared radiation emitted by the Earth. This process increases the overall temperature of the planet, contrary to your assertion.
Profit Motive Allegations: While economic interests can influence policy decisions, the scientific consensus on climate change is based on extensive evidence and rigorous peer-reviewed research. The overwhelming agreement among climate scientists is not driven by profit but by empirical data and the scientific method.
Alternative Heat Source Claim: The idea that there is an unidentified internal heat source that science ignores is unfounded. The sun is the primary external source of heat for the Earth, and the role of greenhouse gases in trapping heat is well-understood and supported by extensive scientific research.
The mainstream scientific understanding of climate change is robust and based on a comprehensive body of evidence. The assertion that profit motives are the primary driver of this consensus misrepresents the rigorous, evidence-based process through which scientific knowledge is developed.
